Application and development of filters in anti-EMI [Copy link]

Application and development of filters in anti-EMI With the continuous progress of science and technology and the gradual improvement of human living standards, household appliances, mobile and personal portable electronic devices are increasing, so the mutual influence and interference between electronic devices are becoming more and more serious and complicated. IBM analyzed computer power failures and believed that nearly 90% of the failures were caused by electromagnetic interference (EMI); in 1994, relevant departments of my country conducted a radio interference performance survey on different models of cars produced by 147 companies, and only 1/4 of the cars met the standards. Electromagnetic interference also threatens human health and safety. Biologists at Heidelberg University found that even weak electromagnetic radiation can invade the brain through the eyes and sow the seeds of cancer in people, so they called on people to be vigilant against "electromagnetic smoke". It can be seen that the harm caused by EMI is no less than tangible pollution.
